CNA Practice Test: Video 1 Answers (25 Questions)

Question 1

What is the single most effective way to prevent the spread of infection?

Accepted Answer

Proper hand hygiene

Answer

Hand hygiene, either handwashing or alcohol-based hand rub, is the most effective way to break the chain of infection. Gowns are used only when contact with body fluids is expected, and CNAs never give medications.

Question 2

When washing hands, the CNA should rub with soap for at least:

Accepted Answer

20 seconds

Answer

CDC guidance is to scrub all surfaces of the hands with soap for at least 20 seconds, keeping fingertips pointed down and rinsing from wrist to fingertips. Shorter times do not reliably remove microorganisms.

Question 3

What is the proper order for removing PPE?

Accepted Answer

Gloves, goggles, gown, mask

Answer

Gloves are the most contaminated, so they come off first, followed by goggles or face shield, then the gown, and finally the mask or respirator. Hand hygiene is performed after removing all PPE.

Question 4

Which observation should a CNA report to the nurse for a resident with a urinary catheter?

Accepted Answer

Cloudy urine with an unusual odor

Answer

Cloudy urine with a strong or unusual odor can signal a urinary tract infection, one of the most common catheter complications, so it must be reported to the nurse. Clear pale urine, a bag below bladder level and kink-free tubing are all normal, correct findings.

Question 5

Before giving any care, what must the CNA always do first?

Accepted Answer

Identify the resident and explain the procedure

Answer

Correctly identifying the resident prevents care errors, and explaining the procedure respects the right to be informed and to refuse. Sterile gloves are not needed for routine care, and bed height is adjusted for the task, not maxed out.
